I have used a pic and a cs5524 (24 bit a/d ) this uses shift in / out commands. I had 19 bits efffectivly. Remember your input circuits need to be layed out carefully to take advantage of available dynamic range.

leonel, have a look at the MCP355x series of Delta-Sigma Converters. I have done some work with the MCP3553 and am planning on incorporating into a new design. They are fully differential and the MCP3553 has a 16Ms. update rate. The series is made by Microchip.

Using MCP3553 probably will work, but my circuit is to be supplied with 4 batteries of 1.5V, +-700mAh. MCP3553 has 170uA of current supply it's a little too much.
I would like to have a consume of about +-20uA.

leonel, In shutdown mode it only draws 1 uA...... In sleep mode it only draws 10uA......
